I have spent A LOT of nights in a tent at 0 or below.
First is a good Winter pad. The Exped that
@Rthur posted or one of their models is what I recommend. Have tried many out. I carry the 32 oz knowing I will be warm and sleep great.
An R value of 9.2 on the Downmat 9 I use is unreal in the cold.
Look at Western Mountaineering bags. Top end like Feathered Friends and they make models with “girth”.
Either one of those companies make solid products.
They also make a variety of lengths for you giant people.
My rule for tent sleeping in cold is fresh socks (I carry a pair just for sleeping) fresh long johns (ones you sweated in while hiking/hunting arent as warm) and a beanie.
I dont wear a lot of clothes in my bag. Kinda ruins the idea of trapping air in my mind.
I have draped my big down puffy over my bag as needed.
I use either a single wall tent (Bibler or Mtn Hardware if 2 people) or a double wall mountaineering tent (north face expedition, 2 or 3 person depending on room you need).
Only issue is condensation in the tent on occasion.
We have 3 shops near me that sell these top end bags, so come to CO.
You can check out bags, smoke a fatty, and go raise hell outside Lowlights house
